Proper ICP Volts?

I just had a P2287 code pop up today. I was kind of surprised because I haven't noticed any running problems.

I want to monitor my ICP voltage but I don't know what it's supposed to be. Any help is much appreciated.

Thanks Bullitt390! Just what I was looking for.

Any idea what is considered acceptable deviation?

For example, % of error, like +/- 5%?

Not sure. I am sure there is some amount of error, but no idea what it could be for the ICP sensor, plus the length of wiring, plus the OBD port.

Best case is to back probe the connector directly and take the voltage reading and run the calculations to eliminate all those wiring variables.

But I likely wouldn't read into it that much and use the OBD reading as a decent ballpark.

I'll get a better idea whats going on as I start to monitor it.

I'd imagine to set the P2287 code it would have to be way obviously out. At least for a brief moment.

This kinda sucks. I'm going on a 3000 mile trip this Friday.

With the early 6.0 the ICP connector pigtail becomes oil soaked and goes whacko... The fix is a new ICP sensor and updated pigtail.

ICPV should be 0.18volts--0.24volts at KOEO
